It seems Facebook is blocking links to NBC.com after the TV network's site was compromised earlier today.

Some Facebook users trying to share URLs from NBC.com are running into an error message explaining that the feature isn't available at the moment. "An error occurred while processing this request. Please try again later," the message reads. The message pops up when posting from www.nbc.com. If you try to click on a link, another message pops up: "This link has been reported as abusive."

We've contacted Facebook and NBC for comment and will update when we hear back. Facebook told All Things D that it takes action when there is "malicious behavior on domains and sub-domains that are being shared," but wouldn't comment on the NBC.com site specifically.

Reports about NBC's brief security breach surfaced earlier today. The network confirmed the hack, adding that no user information was compromised. Other companies, like Bitly and Google, are taking precautions after the breach by warning users before they enter NBC.com that there might be a problem with security.
